Elongated openings 12 and 13 are provided in the cylinder 4 andthe collar 11, respectively, for allowing vertical movement of the bar'7 and the units 9 and 10. A sleeve 14 is disposed concentric with thecollar 11, extends over the openings 12 and 13 and is arranged to movewith the units 9 and 10.

A connecting rod 15 is provided with portions 16 and 1'7 which areadjustably secured to each other by means of a hand-operated adjustingmember 18 which is arranged to be locked in adjusted position by meansof a lock nut 19. The portion 16 is provided with right-hand threads 20and the portion 17 is provided with left-hand threads 21. The upper endof the connecting rod is pivotally secured to the piston 6 at 22 and thelower end of the connecting rod 15 is pivotally secured to a crank shaft23.

l The crank shaft 23 is pivotally supported by bearings 24 which aremounted upon the base 1. A drive gear 25 is rigidly secured to the crankshaft 23 and is operatively connected to a power means, such as a motor26, by means of a chain 27.

An intermittent bottle-moving star wheel 28 is disposed concentric withthe cylinder 4 adjacent a top member 29 which is disposed upon thehousing 2. The star wheel 28 is rigidly secured Ill) to an intermittentactuating wheel which is positioned beneath the top 29 within thehousing 2. The actuating wheel 30 is provided with a plurality of slots31 arranged to receive actuating rollers 32 which are mounted upon arotating member 33.

The member 33 is keyed to a shaft 34 which is supported by bearings 35.The lower end of the shaft 34 is provided with a gear 36 which is inmesh with a gear 37. The'gear 37 is keyed to a shaft 38 which hassecured at its upper end a continuously rotated bottle-moving star wheel39. The gear 37 is operatively connected to a gear 40 which is rotatedby the actuation of the motor through a ring gear 41 and a pinion 42which is keyed to the crank shaft 23.

The liquid filling mechanism B is composed of a vertical stationaryshaft member 43 which is rigidly mounted upon the base 1 as at 44. Arotatable drum 45 is disposed concentric with the shaft member 43 and isarranged to be rotated with respect thereto. A head portion 46 issecured to the drum 45 and is supported together with the drum upon abearing 47 which is carried by the shaft 43. A gear 48 is rotatablymounted upon a stationary stub shaft 49 which rotatably sup ports thegear 40 and is rigidly secured to the ring gear 41 by any suitablemeans, such as machine screws 50. A relatively large gear 51 is securedto the lower portion of the drum 45 and is in mesh with the gear 48. Inthis manner, the liquid filling mechanism is operatively connected tothe driving mechanism.

A plurality of bottle rests 52 is supported by actuating rods 53. Thebottle rests 52 are provided with back portions 54 which have outwardlyextending integral arms 55 for holding the bottles in a verticalposition. An outer sleeve 56 is provided for each of the bottle restsand are slidably disposed in supporting bearings 57 which are integralwith the drum 45. The upper ends of the outer sleeves are secured to thebottle rests. Inner sleeves 58 are provided for each of the outersleeves and are so arranged that the outer sleeves are movably disposedthereupon.

Outwardly projecting guide portions 59 are integral with the drum 45 andare arranged to receive the guide rods 53. Compression springs 60 aredisposed in the sleeves 56 and 58 between the bottle rests 52 and theguides 59'. Cam rollers 61 are rotatably carried by the lower ends ofthe guide rods 53.

An arcuate-shaped cam 62 is rigidly secured to the housing 2 and isdisposed substantially adjacent the drum 45. The cam 62 is provided withan engaging tapered portion 63 so positioned that the cam rollers 61will engage therewith. The cam 62- is then tapered slightly for a shortdistance as at 64 and this portion may be termed as the pressure releasecam portion. The cam 62 has a transversely extending portion 65 whichconnects the pressure release cam portion 64 to the bottle release camportion 66. The opposite end of the cam has an upwardly extendingportion 67 for a purpose hereinafter described.

An adjusting screw sleeve 68 extends through the head portion 46 and isreceivable in the shaft portion 43'. The drum is secured againstrotation to the adjustable screw 68 by means of a key which is held bylocking screws 69 which extend through the head portion 46. A cover 70is disposed upon the head portion 46 and is provided with an internallythreaded opening which is arranged to receive the threads of theadjusting screw 68. A hand wheel 71 is keyed to the cover 70 for apurpose hereinafter described.

A support 72 is mounted upon the upper end of the adjusting screw 68. Afilling tank 73 is mounted upon the support 72 and is provided with aliquid supply pipe 74 which extends through the adjusting screw 68,through the shaft 43, the base 1 and in communication with the watercompartment '75 of a carbonator 76. A gas line 77 provides communicationbetween the gas tank '78 of the carbonator 76 and the filling tank 73through a valve 79. The liquid is maintained at a level indicated at 80.Therefore the upper portion of the filling tank 73 contains air or gasunder pressure.

A plurality of filling valves 81 is disposed around the peripheral edgeof the support 72 in alignment with the bottle rests 52. The fillingvalves 81 are identical in construction. Therefore, a description of onewill apply to them all. The filling valve is composed of a casing 82which has a gas inlet 83 and a water inlet 84. The gas inlet 83communicates with the gas chamber 85 of the filling tank 73 throughtubes 86 and 87. It will be noted that the tube 87 extends through theliquid and terminates substantially adjacent the upper extremity of thefilling tank. The gas inlet 83 communicates with a ball valvecompartment 88 through passageways 89. A ball 90 is disposed in thecompartment 88 and is arranged to be moved in engagement with a valveseat 91 for closing a passageway 92.

A central cutaway portion 93 is provided in the casing 82. An inner orliquid tube 94 is provided with a disc member 95 at its upper end whichis receivable in the cutaway portion 93. A central or gas tube 96 isprovided with a disc portion 97 at its upper end which is receivable inthe cutaway portion 93 when the central tube 96 is disposed concentricwith the inner tube 94. An outer or snift tube 98 is provided with adisc portion 99 which is receivable in the cutaway portion 93 when theouter tube 98 is disposed concentric with the central tu'be 96. Asupporting collar 100 is integral with the disc portion 99 forsupporting the outer tube 98 and used as a stop. Fiber or sealingwashers 101 are disposed between and adjacent the disc portions 95, 97and 99'.

A filling valve tip 102 frictionally receives the lower end of the innertube 94 and is secured to the central tube 962' The central tube isspaced away from the inner tube so as to provide a gas passageway 103therebetween which communicates with gas outlet openings 104 in the tip102. An upwardly projecting liquid outlet opening 105 providescommunication with the inner tube 94 through the tip 102.

A gas valve 106 is disposed in the casing 82 and is arranged to allowgas to pass from the gas inlet 83 through the passageways 89, throughthe ball valve chamber 88, the passageway 92, through the passageways107, passageways 108, and through the passageway 103 between the innertube and the central tube when the valve 106 is in an opened position. Arelatively long valve stem 109 is provided for the gas valve 106 andextends through and beneath the casing 82. A compression spring 110 isprovided for normally holding the gas valve 106 against its seat 111.

A ball valve seat 112 is provided with a passageway 113 whichcommunicates with transversely extending passageways 114 communicatingwith the ball valve compartment 88. This arrangement permits the freepassages of gas from the compartment 88 through both passages 113 and 92immediately upon the opening of the valve 106. The continued upwardmovement of the valve 106closes the passage 113 by the tongue portion115 so that, in event the bottle is broken, permitting the continuedfast flow of gas, this fiow will raise the valve 90 closing the passage92. A tongue portion 115 is carried by the gas valve 106 and arranged toenter the passageway 113 when the valve 106 is in the uppermostposition.

The liquid inlet'84 is in communication with the filling tank 73 througha liquid pipe or tube 116. The liquid inlet 84 communicates with theinner tube 94 through liquid passageways 117, through a ballivalvecompartment 118, through passageways 119, a valve chamber 120, andthrough passageways 121 to the inner tube.

A ball valve 122 is disposed in the compartment 118 and is adapted tocut off communication between the compartment 118 and the passageways119 by moving into contact with the valve seat 123. A valve seat 124 isprovided for the ball valve 122. A compression spring 125 has one enddisposed against the valve seat 124 and the other end in engagement withthe liquid valve 126. The liquid valve is adapted to cut off communi--cation between the valve chamber 120 and the passageways 121. Arelatively short valve stem 127 is provided for the valve 126 andextends through and beyond the casing 82.

A retaining sleeve 128 is secured to the lower extremity of thecasing'82'and is provided with an outwardly extending annular flange 129at the lower extremity thereof. A bell unit 130' is arranged to bedisposed concentric with theretaining sleeve 128 andto be limited in itsdownward movement by the annular flange 129 which engages with a cap 131which is secured to the bell unit. A compression spring 132 is disposedwithin' the retaining sleeve 128 and the upper portion of the bell unit130 for normally holding the bell unit in a downward position. The bellunit 130 is provided with a sleeve portion 133 which mov ably receivesthe outer tube 98. A bottle-sealing portion 134 is disposed'in the bellunit 130 for a purpose hereinafter described.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The manner in which thebottles are fed in and taken from the mechanism is immaterial in thisapplication.

Let us assume that the motor 26 is set in motion. During this motion ofthe motor, the crank shaft 23'will be rotated causing a verticalreciprocatory movement of the piston 6 and the units 9 and 10.Therefore, as bottles are moved into engagement with the star wheel 28,the star wheel will move the bottles intermittently beneath the syrupingunit where a desired quantity of syrup will pass through the unit andinto the bottle from a syrup tank, not shown. It will be seen that theempty bottle will be moved beneath the sy uping unit 9 while the piston6 and the unit 9are in the upward position and that the bottle will beheld stationary and in alignment with the syruping unit as the unit 9'completes its downward movement and until the unit is freed from thebottle.

The intermittent motion of the star wheel 28 is caused by the rotationof the shaft 34 which swings the rotating member 33 about its centercausing the rollers 32 to alternately pass into the slots 31 and rotatethe actuating wheel 30 together with the star wheel 28. The star wheel28 is therefore rotated about one-sixth of a revolution during one-sixthof a revolution of the shaft34 and then remains stationary during thebalance of one-half a revolution of the shaft 34.

After the bottle has received a desired proportion of syrup and moved toone side by the intermittent star wheel 28, the continuously moving starwheel 39 will move the bottle upon the adjacent bottle rest 52. It willbe noted that when the power means, such as the motor 26, is set inmotion, the drum is rotated in a clockwise direction, viewing the top ofthe drum. Therefore as each bottle is moved from the intermittent starwheel 28 by the continuously moving star wheel 39, the drum 45 hasrotated a sufficient distance to bring the next adjacent bottle restinto receiving position for the next bottle.

The bottle rests when in the position for receiving the bottles from thestar wheel 39 are in their lowermost positions which is caused by therollers 61 riding beneath the surface 66 of the cam 62. After the bottleis moved from the rotating star wheel 39, the roller 61 of the bottlerest 52 upon which the bottle is disposed rides upwardly along thesurface 67 of the cam 62, allowing the bottle rest and the bottle tomove upwardly.

As the bottle moves upwardly, the neck or top of the bottle engages withthe sealing portion 134 of the bell unit 130 and causes an upwardmovement of the bell unit against the tension of the spring 132. Thebell unit is moved upwardly and strikes against the valve stem 109.During a continued upward movement, the valve stem 109 is movedupwardly, thus moving the valve 106 from off the valve seat 111 andagainst the tension of the spring 110 until the tongue portion 115 extends within the passageway 113. 1

Immediately uponthe movement of the valve 106 from the valve seat 111,the communication between the gas inlet 83 will be opened allowing thegas or air under pressure to pass through the inlet opening 83, thepassageways 89, through the chamber 88, the passageways 92, 107, aroundthe valve 106 through the passageways 108, the passageway 103, betweenthe inner tube 94 and the central tube 96 and into the bottle throughthe passageways 104.

The speed of the gas passing from the gas inlet 83 and through thevarious pasasgeways into the bottle is sufficiently great to fill thebottle and the passageways with the gas pressure before the valve 106has been moved upwardly a sufficient distance to position the tongueportion 115 into the pa; sageway 113. Therefore the gas may first passthrough both the passageway 92 and the passageways 114 and 113. If thebottle should become broken or chipped so as to allow the gas to escapetherefrom, the tongue portion 115 will stop the free passage of gasthrough the passageways 114 and 113 and the onrush of gas will force theball valve 90 against its seat 91 and close the passageway 92. This onlyoccurs however when the bottle is chipped or broken.

Let us assume that the bottle is not chipped or broken and is filledwith gas under pressure. By pressure I mean gas at approximately fiftypounds pressure. entering the bottle will also enter the inner tubethrough the passageway 105 and pass upwardly to the valve 126. As thebell unit is moved still further upwardly, it engages with the lower endof the valve stem 127 and moves the valve stem and the valve 126upwardly. Immediately upon moving the valve 126 from its seat the gasunder pressure will pass upwardly into the chamber 118. The purpose ofthis is to prevent the rapid flow of the liquid through the inlet 84 andto prevent The gas under pressure in so I the ball 122 from seating, butto allow the liquid to pass at a moderate rate of speed from the inlet84 through the passageways 117, through the compartment 118, through thepassageways 119, the valve chamber 120, around the valve 126,

through the passageways 121, through the inner tube 94 and through thepassageway 105 into the bottle.

The passageway 105 is tapered slightly upwardly so as to direct theliquid upwardly through an are so that the water or liquid will contactwith th inner wall of the bottle without causing any disturbance of theliquid. In this manher, the liquid will flow down the inner wall or" thebottle and fill the bottle to the outlet air openings 104.

The purpose of allowing gas under pressure to enter the bottle prior tothe filling of the bottle with liquid is to allow the liquid to enterthe bottle filled with gas pressure and provide a cushioning efiect forthe liquid so as to avoid disturbance thereof. If the bottle is chippedor broken so as to prevent a perfect sealing, the gas under pressurewhich passes into the bottle after-the valve 106 has been opened willescape therefrom causing the ball valve 96 toclose and prevent thefurther escapement of gas. Also the counter gas pressure whichis againstthe ball valve 122 when the bottle is in good condition is eliminatedand the liquid in passing rapidly into the compartment 118 will forcethe ball valve 122 against its seat 123, thus shutting 011 the flow ofthe liquid.

Assuming that the bottle is in good condition and the bottle has beenfilled with the liquid, there will remain a top pressure between thelevel of the liquid and the top of the bottle. A special means isprovided for releasing this top pressure gradually so as to prevent anydisturbance of the liquid when the bottle is released from the fillingvalve. This means consists in the provision of a snift valve 135 whichis loosely mounted in a bushing 136 in the casing 82. The valve 135 isarranged to seat at 137 for closing an air passageway 138 whichcommunicates with a passageway 139 between the outer tube 98 and thecentral tube 96 by means of passageways 140 through the discs 95 and 97and a passageway 141. A needle valve 142 is adjustably carried by thecasing 82 and is arranged to vary the speed of the gas in passingthrough the passageway 141.

A sliding valve lever 143 is pivotally mounted at 144 to the casing 82and is provided with an arm 145 which extends inwardly in engagementwith the valve 135. A tension spring 146 is adapted to hold the valve135 normally in closed position. A cam 147 is integral with the bellunit 130 and is arranged to engage with the valve lever 143.

The tapered portion 67 of the cam 62 allows the gradual upward movementof the bottle rest causing the bottle to engage with the bell unit andmove the bell unit upwardly so as to first open the valve 106, fill thebottle with gas under pressure, and then opening the valve 126 so as toallow the liquid to enter the bottle under pressure. When this has beenaccomplished, the roller 61 has been moved free from the cam 62 by therotation of the drum 45, and during the rotation of the drum the liquidslowly passes into the bottle.

By the time the bottle reaches the position whereby the roller 61 of therest 52 thereof reaches the cam 62, the bottle will. be filled with theliquid. As the roller engages with the surface 63 of the cam and therest 52 is moved downwardly together with the bottle and the bell unit,the liquid valve 126 and the gas valve 106 will be released and allowedto close, thus cutting off the flow of the liquid and the gas. As theroller 61 passes upon the surface 64 of the cam 62, the bell unit 130will have been moved downwardly a suflicient distance to cause the cam147 to engage with the valve lever 143 and swing the lever about itspivot and move the shift valve 135 away from its seat 137. During thisoperation the bottle is still sealed.

It will be noted that the outer tube 98 terminates a short distance fromthe filling valve tip 102, thus allowing the top pressure or that gaspressure in the bottle between the upper level of the liquid and the topof the bottle to escape through the passageway 139, the passageways 140and 141, by the needle valve 142, through the passageway 138, around thevalve 135, through the opening in the bushing 136, and out into theatmosphere.

By the time the roller 61 reaches the transversely extending portion 65of the cam 62, the top pressure will have been allowed to escape. As theroller 61 passes downwardly over the surface 65 and upon the surface 66,the bottle rest together with the bottle will be drawn downwardly totheir lowermost positions releasing the bottle from the bell unit.Before the bottle is released, however, the gas valve 106 is closed andthen the valve lever 143 is released allowing the spring 146 to move thevalve against its seatl37.

The filled bottles are taken from the bottle rests by the rotating starwheel 39 and moved into engagement with the intermittent moving starwheel 28. The star wheel'28 receives the filled bottles and moves themone at a time into a position beneath and in alignment with the crowningunit as an empty bottle is movedinto alignment with the syruping unit 9.The star wheel 28 holds the empty bottle under the syruping unit and thefilled bottle under the crowning unit as has been heretofore described.While the star wheel 23 is at rest, the units 9 and 10 will bemoveddownwardly into engagement with the bottles placing a desiredamount of syrup in the empty bottle and crowning the filled bottle. Thefilled bottles are then moved by the star wheel 28 upon a conveyingmeans, not shown.
